目的观察循证护理模式下的低盐饮食干预对老年高血压患者院外低盐饮食依从性的影响.方法选取昆明医科大学附属延安医院老病科,2014年3月至2017年1月收治的640例老年高血压患者,采取随机数字表法分为对照组(320例)与观察组(320例).对照组采取传统低盐饮食宣教方法,观察组采取循证护理模式下的低盐饮食宣教方法,对2组患者分7个时点(出院当日、出院后2周、出院后1月、出院后3月、出院后6月、出院后9月、出院后12月)进行低盐饮食认知行为评分及每日盐摄入量的对比分析.结果观察组与对照组的低盐饮食认知评分对比,除出院后2周,其余6个时点的比较差异均有统计学意义(P<0.01);观察组与对照组的低盐饮食行为评分对比,7个时点的比较差异均有统计学意义(P<0.01);观察组与对照组的每日盐摄入量的对比,7个时点的比较差异均有统计学意义(P<0.01).结论通过循证护理模式下的低盐饮食干预,可以提高院外老年高血压患者的低盐饮食认知行为评分,降低每日盐摄入量.故循证延伸干预对提升院外老年高血压患者低盐饮食依从性效果显著. Objective To observe the effect of low-salt diet intervention on the compliance of low-salt diet in elderly patients with essential hypertension under the mode of evidence-based nursing.Methods 640 cases from March 2014 to January 2017 in Yanai Hospital Affiliated to Kunming Medical University Patients with senile hypertension were divided into control group (320 cases) and observation group (320 cases) by random number table method.The control group adopted the traditional low-salt diet education method, the observation group took the low salt diet education method under the evidence-based nursing mode , Two groups of patients were divided into 7 time points (discharge day, 2 weeks after discharge, 1 month after discharge, 3 months after discharge, 6 months after discharge, 9 months after discharge, 12 months after discharge). Behavioral score and daily salt intake.ResultsCompared with the low-salt diet cognitive score of the observation group and the control group, except for 2 weeks after discharge, the other 6 time points had significant difference (P < 0.01). Compared with the control group, the scores of low-salt diet behavior of the observation group and the control group were significantly lower than those of the control group (P <0.01); the daily salt intake of the observation group and the control group was 7 There were significant differences at one time point (P <0.01) .Conclusion Evidence-based nursing Low-salt diet intervention can improve low-salt diet cognitive behavior scores of elderly patients with hypertension in hospital, reduce the daily salt intake. Therefore, the evidence-based extended intervention to enhance the compliance of low-salt diet of elderly patients with hypertension outside the hospital Significant effect.
